Is it possible to simulate settling of solid particles suspend in liquid?

Track one particle or 'many'?

settlingFoam in anycase would be a good start. BubbleFoam can also be modified for this purpose.

twoPhaseEulerFoam should be easier to adapt to your purposes than bubbleFoam because it already contains two particle models:

- Normal stress modulus
- Kinetic theory approach (which is not yet very stable)

Best regards,

Thanks guys! In reality, th
Thanks guys!

In reality, there are several thousands solid particles suspended in liquid. I will be happy to track maybe 10 particles. I will look into settlingFoam first.

Well, with the codes aforement
Well, with the codes aforementioned, no particles is tracked, they all use a eulerian approach. Assuming that with several thousands of particles you have a dense two-phase flow, either can be chosen.
SettlingFoam : based on drift flux model with mixture equution for mass and momentum
twoPhaseEulerFoam/bubbleFoam: two-fluid models.

rock dumping
Hi Pierre,

I want to know which solver i can modify when you have a vertical pipe with rocks inside. Hereby i want to model first one solid particle and extend to more particles.
Hopefully you can advice me.

I would look here
